Abstract: A mixture containing mixture one or more amines, water, low-boilers and high-boilers, is fractioned in a process wherein (i) low-boilers are separated from the mixture by distillation, (ii) high-boilers are separated from the mixture by distillation, (iii) the mixture is extracted with a sodium hydroxide solution to form an aqueous, sodium-hydroxide-containing first phase and an aqueous-organic, amine-containing second phase, and (iv) the aqueous-organic second phase is distilled to form an amine/water azeotrope and an essentially anhydrous amine, and the amine/water azeotrope is recycled to the extraction step (iii).

Abstract: A process for preparing chromanol derivatives of the formula I ##STR1## where n is from 1 to 10,R.sup.1, R.sup.2,R.sup.3, R.sup.4 independently of one another are hydrogen or C.sub.1 -C.sub.4 alkyl,R.sup.5 is hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.6 -C.sub.10 aryl, C.sub.7 -C.sub.18 aralkyl, C.sub.7 -C.sub.18 alkylaryl, C.sub.1 -C.sub.22 acyl, or a group protecting the hydroxyl,by reduction of the corresponding 4-oxochromanol derivatives of the formula II ##STR2## comprises reacting the 4-oxochromanol derivatives of the formula II with metallic zinc in the presence of an acid or an acid mixture.Compounds of the formula I having C.sub.1 -C.sub.22 acyl as radical R.sup.5 can also be prepared by the above-described reduction of the compounds of the formula II with hydrogen as radical R.sup.5 and simultaneous or subsequent esterification.

Abstract: A process for preparing alkyl 2-alkyl-4-fluoromethylthiazolecarboxylates of the formula I ##STR1## where R.sup.1 is alkyl,R.sup.2 is difluoromethyl or trifluoromethyl andR.sup.3 is alkyl,by reacting thiocarboxamides of the formula II ##STR2## where R.sup.1 has the abovementioned meaning, with alkyl 2-chloro-4-fluoroacetoacetamides of the formula III ##STR3## where R.sup.2 and R.sup.3 have the abovementioned meanings, in an aprotic solvent at below 100.degree. C. and reacting with a dehydrating agent, in the presence of a base, at below 80.degree. C. is described.

Abstract: .alpha.,.beta.-Dihaloalkyl isocyanates and a process for the preparation of such compounds by reacting .alpha.,.beta.-unsaturated alkyl isocyanates with halogen in the presence of an organic solvent which is inert under the reaction conditions, at from -35.degree. to +90.degree. C. The .alpha.,.beta.-dihaloalkyl isocyanates thus obtainable correspond to the formula ##STR1## where R.sup.1, R.sup.2 and R.sup.3 are identical or different and each is hydrogen, a saturated aliphatic radical of 1 to 10 carbon atoms, a cycloaliphatic radical of 3 to 12 carbon atoms, an araliphatic radical of 7 to 11 carbon atoms or an aromatic radical of 6 to 10 carbon atoms, or R.sup.1 and R.sup.2 together with the carbon atom on which they are present as substituents are cycloalkyl of 3 to 7 ring members, and X is halogen. The compounds are valuable intermediates for the preparation of dyes, surface-coating intermediates, crop protection agents and drugs.
